They were used in the various versions of the System One and System Three (CS-1, CS-3, CS-100); Z systems didn't have keylocks, and the other (later) CS-x00 (200, 300 and 400) series used the KABA flat keys with dimples (which were also all the same number AFAIK, EB0001). http://www.computercloset.org/CromemcoSystem1.htm http://www.oldcomputers.net/cromemco-system-three.html http://www.dantiques.com/computers/cromemco/100300.htm https://en.wikipedia.org/wiki/Cromemco KABA keys: http://www.lockpicking101.com/viewtopic.php?f=9&t=57825 Some models also used 'normal' keys for access to the card cage etc. > Also - before we get too wide on the systems tracked... the "standard" ace > key had a barrel outer diameter of 0.375" and 7 positions.

If I can find my micrometer I'll measure them; wasn't there an old thread about Ace key codes? m
